| 中文摘要: |
| 目的 基于直驶效率数据，实现机电复合传动系统的性能退化评估。方法 将机电复合传动系统全工况测试周期内的效率云图进行梯度和网格划分，得到各梯度内的网格点数。通过Pick定理，计算各梯度下不规则效率云图的面积，对各梯度效率云图面积求和，即可得到该测试周期内的机电复合传动系统性能退化评估指标。结果 计算了6个全工况测试周期的效率云图面积，结果显示，性能退化评估指标逐渐上升。通过效率云图对比发现，高效区间逐渐增大。从性能退化指标的发展趋势看，目前该传动系统正处于磨合期。结论 该方法能够有效评估机电复合传动系统的性能退化情况。 |

| The work aims to evaluate the performance degradation of the electro-mechanical transmission (EMT) system based on direct driving efficiency data. Gradient division and grid division were conducted respectively on the efficiency pattern of the electro-mechanical transmission system during the full working condition testing cycle, and obtain the number of grid points within each gradient. The area of the irregular efficiency pattern under each gradient was calculated using Pick's theorem, and the efficiency pattern areas of each gradient were summed up to obtain the performance degradation evaluation index of the electro-mechanical transmission system during the testing period. The efficiency pattern area was calculated for six full cycle testing cycles. The results showed that the performance degradation evaluation index gradually increased. Through the comparison of efficiency pattern, it was found that the efficiency range gradually increased. From the development trend of performance degradation indicators, the electro-mechanical transmission system was currently in the running period. This method can effectively evaluate the performance degradation of the electro-mechanical transmission system. |
